IMPA1

mass-spec protein & survival
Survivalmass-specKaplan–Meier · TCGA cohorts

Across TCGA pan-cancer cohorts, IMPA1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated IMPA1 data layer compared with 22 for mass-spec protein and 7 for mutation status.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher IMPA1 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated IMPA1 expression acts as an unfavorable survival marker, although some lineages such as PDAC and CCRCC show a favorable association.

PDAC, CCRCC, and LUAD are the cancer types where IMPA1 mass-spec protein most reproducibly stratifies survival.

mass-spec protein survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
